Weekends and unscheduled days aren't grey anymore. Terrible to visualise and allocate hours

It was used to be a little less hard to allocate project hours for staff in Replicon, but now the Weekends and Unscheduled days are no longer grey, making it way harder to visualise and allocate hours.

I contacted the support but nothing can be done about and their solution was suggesting me to post here. As if this would solve anything. But here it is.
